High CPU usage and can't install antivirus

My laptop has been slow for a while (>year). It keeps going to 100% CPU usage (it lags alot and sometimes exetrly badly). I A few months ago I installed Microsoft security essentials. It was alright but it never made my computer faster.

About a month ago I checked online for reasons for slow computers and I suspected it may be malware so I downloaded Malwarebytes anti malware. After scanning with that my computer it sped it up alot and seemed almost normal. However, the next day it was slow again and no future scan helped my performance.

A few days ago I installed hitman pro trail as a second opinion antimalware but despite finding 241 PUP including a trojan, no performance increase occured. A couple days ago I thought about installing AVG internet security trail or bitdefender as they seem better than my current antivirus: MSE. I uninstalled MSE in control panel then i tried to install AVG internet security, but i got an error which i've attached as an image. After that when I tried to install bitdefender I got two different errors which i've also attached as images. The only antivirus I have now is windows defender now which I'm pretty sure is outdated.

Regarding the high CPU usage, I have checked task manager and saw that SVC host was using alot of processing and have been trying to figure out why for a while but I never found out. My computer runs fine in diagnostic startup running only core drivers, etc but normally and in safe mode it lags so I reckon it's something using SVChost causing the problem but I don't know, it could be something else.

I got this laptop a couple years ago in cash converters preowned and it was really good. The problems only came about once I started using the internet a little over a year ago.

Yesterday I did a malwarebytes threat scan followed by a hitman pro scan but both came up clean but i haven't been able to run an antivirus except windows defender which also came up clean.

In conclusion, I really need help figuring out whats wrong. Any help would be appreciated. Also, I've got my system specs attached as an image.

Open the TDSSKiller folder and doubleclick on TDSSKiller.exe to run the application, then on Start Scan.

If an infected file is detected, the default action will be Cure, click on Continue.

If a suspicious file is detected, the default action will be Skip, click on Continue.

It may ask you to reboot the computer to complete the process. Click on Reboot Now.

If no reboot is required, click on Report. A log file should appear. Please copy and paste the contents of that file here.

If a reboot is required, the report can also be found in your root directory (usually C:\ folder) in the form of TDSSKiller_xxxx_log.txt. Please copy and paste the contents of that file here.

Before following your advice i tried to install updates for windows which screwed up, so i had to do a system restore. I tried to download AVG AntiVirus FREE and was successful but despite finding 92 things my computer's still slow. Also, my computer does actually run well in safe mode and safe mode with networking. Also, my hijacked browser is Google chrome.

minitoolbox froze when 'list ip config' was checked so i ended it with task manager. It just keeps freezing on 'getting ipconfig' each time i run it so i left 'list ip config' unchecked. The results of the minitoolbox are below.

ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.

When the scan completes, click List Threats

Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.

Click the Back button.

Click the Finish button.

NOTE:Sometimes if ESET finds no infections it will not create a log.

How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook

Before coming back to the forum to follow your advice I couple weeks ago I set IP helper to manual startup as it was using very high CPU and I didn't seem to need it after looking on the internet. After my next boot my computer was much faster and had been so ever since. I'm not sure if it's normal performance but there is usually no lag at all anymore and my CPU goes to around 0% alot. However, it does take around 10-15 minutes to stabilise after startup and when my internet disconnects or connects it lags for a few minutes.

Now, about the advice, I clicked on reset chrome in a new tab and the URL that appeared in the URL bar was "reset/" and it says "this webpage is not available" on the page. I then went into chrome settings and looked at the "reset settings" option. Is this the same thing, or not? If not, is there something else i can do to reset chrome/?
